Simpsons Porno Story: Bart’s Midnight Escapade

Bart’s Midnight Adventure.
Bart crept quietly down the hallway to the bathroom, it was midnight and because he had an extra can of soda he needed to pee. Marge had told him it would happen so he needed to be very quiet or she would growl at him. As he passed Lisa’s room he heard her talking but could not hear what she was saying, it was like a low whisper. He hurried on to the bathroom wondering who she was talking to. Had she taken the phone up to her bedroom to make secret calls in the night? He hurriedly but quietly finished his pee and crept back to Lisa’s door. He could still hear here whispers.
Very carefully he opened her door the whispering went on but he still could not hear what she was saying. He pushed the door wider. By now his eyes were accustomed to the darkness and with a little moonlight he could see her on the bed. The blankets had been pushed to one side, her legs were open and her nightie was pulled up. She was still asleep! She was talking in her sleep! Bart suddenly realised that this could produce some golden treasure to use against her if he could hear what she was saying.
He slid into her room and closed the door. He moved slowly over to the bed. As he got closer he started to hear some of the words more clearly, he caught “Milhouse” and “harder” the rest was still a jumble. Now he was close enough to see she had one hand between her legs so he moved towards the end of the bed. Now he could see that she had two fingers sliding in and out of her pussy and in the moonlight Bart saw the glisten of wetness on her fingers and on the soft mound of her pussy lips.
Now he was getting very close and realised that some of the sounds were little groans with a few words every now and then. As he listened he could make out enough for him to realise she was dreaming about fucking Milhouse. This was too good! He could hear her asking him to go harder, to rub her tits and squeeze her nipples. Bart suddenly felt his own cock getting harder, from the way she was acting he was sure she had actually, not just in a dream, fucked Milhouse! This was getting better and better! Now he had something on Milhouse too.
Bart watched, then slowly reached out and lightly touched Lisa’s left nipple and ran his finger slowly round it the he traced his finger across her chest to the other nipple and did the same. Lisa shifted slightly but showed no sign of waking so Bart covered her breast with his hand and gently squeezed and caressed it, this time she reacted by pushing up against his hand and moaned Milhouse’s name.
Bart very slowly moved his hand down her belly just letting his fingertips trace lightly on her skin at the same time he leant forward and very gently licked then sucked on her nipple. This time she shifted and moaned louder, Bart started to worry that Marge would hear her so he drew back from sucking and licking but slid his hand down further. At this point Lisa hard sped up her fingering and she was certainly getting very wet. Her breath was also coming faster. Bart’s fingers reached the dampened area of her soft pussy mounds and the soft warm dryness became slightly slippery. With two fingers Bart gently pushed slowly downward making sure not to get in the way of Lisa’s working fingers. Lisa shifted again moaned Milhouse’s name and opened her legs wider. This gave Bart a very good view of her glistening wet pussy and her fingers as they pushed in and out of it. He let his fingers slip into the top of her slit. He gently rubbed, with one finger, her hardened clit. He heard her call out “Yes, Yes Milhouse do it.” Her Fingers slipped out of her pussy and Bart slipped his in in their place. He thought that Lisa was believing that Milhouse was really there. With two fingers pushing as deeply as possible without waking her.
Bart could not resist leaning forward again and pushing his tongue into her wet slit and started to suck on Lisa’s clit. Her hips started to lift against his fingers and mouth. Her wetness was sweet and oily. Bart slowly increased his speed and Lisa got wetter, now she was asking Milhouse to fill here with cum. Her hips were thrusting harder and faster, Bart’s fingering got a bit harder. Bart started to stroke his cock, it was now very hard. As he himself got close to cumming he stopped sucking and licking Lisa’s clit and watched her face for any sign that she was waking. He was amazed that she was stilled deeply asleep. All of a sudden she stiffened and pushed up hard against his hand. He felt her pussy spasm along with a release of hot cum out along his fingers. As she came Lisa hissed I’m cumming!! Milhouse cum in me!!
At that instant Bart felt his cock starting to throb, he could not stop it and suddenly there was cum squirting through his fingers over Lisa’s pussy. Lisa shuddered as it sprayed over her. Bart slipped his fingers out of her pussy. Lisa sighed closed her legs and rolled over on her side and with a final “Oh Milhouse” she slipped into a deeper sleep.
Bart stood fixed to the spot, cum still dripping from the now soft cock. His mind was now working very hard. How could he use this? His sister’s sweet wet pussy was so tight and hot and she went off like a fire cracker when she came. There had to be a way that his cock was buried in that hot wet hole when she was dong that. Quietly he edged to the door, slipped out and went to his bedroom. He slipped into bed and was soon asleep.
The next morning Bart heard the shower running, it was still early. The sight of what had happened in Lisa’s room came flooding back and his cock started to harden. He let the thought subside and his cock did too. It was time to start the campaign! He went down to the bathroom and breezed in, Lisa was in the shower.
“ Oh sorry Sis, I thought it was Dad as you had a shower before bed last night, why another one this morning?”
“ Get out! Bart!”
“Ok Lisa, nice body by the way. What does Milhouse think of it?”
Bart slipped quickly out of the room as Lisa threw the soap at him. He grinned and headed for the kitchen. He peaked into Lisa’s room and saw that she had changed the sheets, he realised that the nightie in the bathroom was not the one she had on last night. Bart grinned to himself. He now knew she knew that he knew.
Let the negotiations begin!
